Abstract
The article corrects two often repeated errors about John Hatton (d. 1815, Baltimore County, Maryland). One states that his widow Ann was the mother of all of his children. The other states that his birth year was c. 1743.
After identifying John Hatton's widow as Ann Holland, the article presents evidence that they married in 1793 or later. All but one of his children had a mother other than Ann.
Indirect evidence pertinent to John's birth year is discussed. The range of possible years is narrowed to 1752-60. Support for estimating his birth year as c. 1756 concludes the article.
